摘要： Anisotropic graphite and an anisotropic graphite composite are provided, each having excellent heat transmission performance and excellent long-term reliability as a heat transmitting element, and a production method for the anisotropic graphite composite. A face of anisotropic graphite which face is perpendicular to crystal orientation planes of graphite layers of the anisotropic graphite may be subjected to surface treatment so as to obtain anisotropic graphite having a specific surface roughness. An anisotropic graphite composite may include anisotropic graphite having an interface that has a specific interface roughness; a titanium-containing metal layer; and an inorganic material layer.

摘要： A re-forming process is carried out in which a material graphite film is heat-treated to not less than 2000° C. while the material graphite film is being pressured. Through the re-forming process, sag of a graphite film is controlled. By using, during the re-forming process, a plurality of inner cores having respective different surface states, it is possible to produce a graphite film having two or more sag forms which have respective effects.
